To all whom t may concern: Be it known that LLEWIs S. BROWN, of Columbus, inthe county of Franklin and State of Ohio, have invented a new and Improved Coin-Controlled Tire-Pump, of which the following is a full, clear, and exact description. Myinvention relates to an improvement in pumps intended for use in filling the tires of bicycles and controlled by a coin, the pump being released or p ut in operative 'position by the insertion of a coin and thrown into inoperative position bythe removal of the wheel.

My invention consists of certain novel features of construction, whi ch will be hereinafter described and claimed. t Referenceis to be had to the accompanying drawings, forming a part'of this specification, in which similar characters of reference indi-A cate corresponding parts in all the views.

Fig. 3 is a top plan view of the casing containing the Wheel-support and the controlling apparatus.l Fig. 4f is a side elevation, with one face removed, of that portion of the casing containing the controlling mechanism. Fig. 5 is a similar view of a portion of said casing, showing the parts in a different position. line 6 6 of Fig. 4. Fig. '7 is a cross-section taken upon the line 7 7 of Fig. 4, and Fig. 8

is'a cross-section taken upon the line 8 8 of;

Fig. 4:.

The object of my, invention is to providea device within whiohawheel' maybe inserted and connected with ai hose Jfor the purposeof pumping up the tire, the said device being provided with a pump and the connection be ing made between the pump and the tire by.

inserting a coin in the device. Aframe A is mounted upon a suitable stand and is provided with two hooks B and Bl of 1 such size and so placed as to receive the lower portion of a bicycle-wheel. To this frame is connected a vertical standard A', upon which is secured a third hook B2, adapted to engage the upper portion of a bicycle-wheel, so as .to give the same a sure support.

Mounted upon the base alongside the frame A is a pump-cylinder P, consisting of a pisanism is fnot essential.

'the two portions p and p of a hose.

Fig. 6 is a cross-section taken upon the ton which is operated by means of a rodMS, which extends upward through suitable guides on the standard A', said standard consisting of two parallel members connected at their upper ends by an integral cross-bar, Which bar is shown broken away in Fig. 1. To the rod M3 is pivoted a connecting-rod M2, which at its other end is pivoted upon a crankwheelM, mounted upon the same shaft as the wheel M, the latterbeing a fly-wheel provided with a crank or other suitable mechanism, by which it is to be revolved. The eX- actconstruction of the pump-operating mech- Any form of operating mechanism may be substituted for that described.

The upper portion of the frame A `is provided witha casing C, provided with a chamberc, adaptedto receive the mechanism-by which the device is'controlled, and :with'a receptacle C' to receive the coins. Thiscasing has at one enda block R, which formsavalvecasing, and is provided at top and bottom with means, as nipples p2, for the attachment of The lower section p of the hose is attached to the pump, while the upper section p' is adapted to be connected with the tire. The block R has an aperture therethrough forming a seat for the controlling-valve. This valve is formed as a part of a rod D, -which extends lengthwise of the casing C and is provided with a port d, adapted at will to form a connection between the pump and the tire or between the pump and the outer air. The block R, forming the valve-casing, is provided to the connection with the tire. The port d v through the Valve is adapted to connect the port leading to the pump with the one lead- Eing to the tire or tofconnect the portleading ,to the pump with' the one leading to the outer air. This valve is of the same-nature as the yordinary three-way valve.-

Upon the rod D, which forms the valve, is secured a segment-arm E, to which is connected one end of a spring e, secured at its opposite end to the casing and acting to throw the arm E toward the coin-controlled lever G.

`with three ports or passages,`one port D lead- -ingfrom the valve to the pump connection, another D2 leading from the valve to the outer air, and the third D3 leadingfrom the valve IOO This lever G is pivoted at g to the side of the easing C and has one end entering the narrow channel G2, formed in the bodyof the casing and covered by a plate II. The upper portion of the channel G2 is connected with the coin-receiving chute J, which is here shown as formed by securing a separate piece tothe upper side of the casing. The chute is provided with an additional channel J', located immediately beneath the aperture through which the coin is inserted. This passage J is of such a width that the coin for which the device is intended will slide along the passage, while a smaller object will slip through it, and thus not act on the lever G. A coin dropped in the chute will rest upon 011e end ot the lever G and throw the opposite end upward, so as to remove it from the path of the segment-arm E. The rod D, carrying the segment-arm E, is also provided with an arm or radial pin F, extending through a slot in the plate II in such a position as to limit Jthe downward swing of the lever G and prevent the discharge of the coin I.

To enable the pump to be connected with the wheel, the valve must be turned so as to make a direct connection between the ports D and D3. In its normal position the valve is set so as to make a connection between the ports D' and D?. The segment-arm E, en gaging the end of the lever G, will prevent the valve from being turned until a coin has been dropped into the chute. Then the lever G has been thrown up by the coin, the valve may then be rotated so as to make the connection between the ports D and D3. As the rod D is rotated the arm or radial pin F is swung downward, thus permitting the lever G to drop farther and to release the coin. The periphery of the segment-arm E will engage the under edge of the lever G and prevent its dropping until the valve has been turned backward.

The hook D', which engages the bicyclewheel, has an arm or hook 7) pivoted thereon by the pin b'. llvhen this hook Z) is swung t0- ward the outer end of the hook I3, it will pass over the inner side of the bicycle-rim and lock the same in place. Upon the outer end of the rod D, which forms the valve, is liked a lever II, and this lever is connected by a link 7s to the hook Y), so that the two are operatcd together. The hook b and lever K are provided with apertures b2, adapted to receive the lilik 7.: and by which the relative throw of the hook I) and lever K may be adjusted. The upperend of the leverK is protected by a casing L, formed of plates secured to the end of the easing C.

The operation ot my device is as follows: The normal position of the parts is that shown in Figs. 2, 3, and .i, in which the hook Y; is open, and the valve D connects the ports D and D?. Vith the parts in this position the bicycle-wheel is placed within the supporting-hooks B, B, and I3?. A coin I is then inserted in the chute, which as it drops on the end of the lever G throws the other end of the lever up, so that the valve maybe turned into its operative position. This is accomplished byen gagin g the lever K and turning the valve into the position shown in Fig. 7. After tho upper section p of the hose has been connected to the tire the pump may be operated to inflate the tire. lVhen the tire has been inflated, the lever K is thrown backward to the position shown in Fig. 2. This releases the wheel and at the same time permits the lever G to drop from the position shown in Fig. to that shown in Fig. 4, in which the valve-stem is locked, so that the pump cannot be used to furnish air for another tire until another coin is inserted in the chute J. By this means a coin must be inserted in the device for each tire inflated.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A tire-pumping device, comprising a pump, a tube leading therefrom and adapted to be connected with a tire, a valve interposed in said tube, a wheel-lock, connections between the wheel-lock and the valve, whereby the tire connections are broken when the wheeldock is open, and a coin-released mechanism for controlling said parts, substantially as described.
